My invention relates to convertible stripping, inserting and drawingtables such as are employed in the commercial photography and graphicarts, and has for one of its objects the provision of means wherebyphotographic negatives and the like can accurately and conveniently bepositioned or aligned preliminary to the making of half-tones, zincetchings, etc.

Another object of my invention is to provide a structure of thecharacter referred to, which is useful as a layout table, cutting table,or a drawing board for artists or draftsmen.

Some of the forms which my invention may take are shown in theaccompanying drawings wherein Figure 1 is a plan View of one form oftable; Fig. 2 is an elevational view thereof; Fig. 3 is an enlarged Viewtaken on the line III- Ill of Fig. 1; Fig. 4 is an enlarged view takenon the line IV-IV of Fig. 1; Fig. 5 is an end view of one 2()` of theT-square elements of Fig. 1; Fig. 6 is a plan view thereof; Fig. 7 is aview taken on the line VII-VII of Fig. 6; Fig. 8 is a plan view of aprotractor for use with the table; Fig. 9 is an enlarged view taken onthe line IX--IX of Fig.

8; Fig. 10 is a view showing a modification of the structure of Fig. 1;Fig. 11 is an enlarged plan view of a portion of the structure of Fig`10; Fig. 12 is an end view thereof; Fig. 13 is a plan View showing stillanother modification, and Fig.

14 is an enlarged sectional View of one of the aligning fingers and itsmounting of Fig. 13.

Referring first to Figs. 1 and 2, the table comprises a rectangularframe that is composed of angle bars I0 connected at the corners of theframe by corner blocks II. The lugs I2 aresecured to the undersides ofthe angles I0 and serve to support a glass plate or board I3 upon whichthe lm negatives or drawing paper may be placed. The table is providedwith legs I 4 that are connected to the underside of the framework byinserting them through hubs I5 that are carried by the corner bracketsII, the legs being held in the hubs by set screws I6, as shown moreclearly in Fig. 4. Three of the hubs carry brackets I1 .15 whosesleeve-like portions surround the hubs and are held in place thereon byset screws I8. Guide rods I9 and 20 are carried by the brackets I1, thereduced ends of the rods I9 and 20 being journalled in the brackets, foroscillatory movement. One reduced end of each rod extends through abushing 2I, which bushing is rigidly held in the bearing portion 22 ofits associated bracket. Beyond the bushing 2I `the rods are threaded forthe `reception of draw-up nuts 24 and locl; nuts 25. The nuts 24 aredrawn up (Cl. {i3-184.5)

sufciently to draw the shoulder portions of' the rods against the innerends oi the bushings, to prevent end play or axial movement of the rods,while still permitting them to rotate in the bushings.

Slidably mounted on the rods I9 and 20 are T-squares 2B and 21respectively. Each T-square comprises a straight-edge element anda headportion 28, which is of generally tubular form and has the straight-edgeconnected thereto by 10 screws 29a. Each head 28 is provided with alocking or set screw 29 which has engagement With the associated guiderod to hold the T-square in set positions. The body portions of theheads 28 have bores for the reception of recessed presser 15 blocks 30that bear against the guide rod and Whose inner ends are curved to thecontour of the rod (Fig. '7). Coil springs 3| seat within the presserblocks, and studs 32 are threaded into the bores and hold the springsagainst the presser 20 blocks with a desired degree of tension. As shownin Fig. 1, the T-square 26 overlies the T-square 21, it being understoodthat the head 28 which carries the member 26 is of such thickness orheight as to support the member 26 in a 25 slightly higher plane thanthe member 21. Furthermore, since `the T-squares are shown as oi verythin material, they will flex suii'iciently to permit one to overlie theother, even though their base ends are disposed in a common plane. 30

`color photography where several plates are required for printing apicture, and if each negative 40 is not accurately aligned on the tablepreliminary to reproducing it for printing purposes, the colors will notbe matched properly in the printed picture. In order to prevent suchlooseness, the springs 3l are maintained under suflicient ten- 45 sion,by adjustment of the screws 32, to prevent play of the heads 28 on theirguide rods, Vbut still to permit convenient rocking and sliding of thestraight-edges. In other words, the presser shoes and their springsmaintain the wall of the heads 50 at the opposite side in close contactwith the guide rod, during alignment of the T-squares with the negativesor other material being set up. When the straight-edges have been movedto a desired position, the set screws 29 will be turned to clamp 55 vthe plate or board, without disturbing the adjustments of thestraight-edges.

Locking dogs 34 are provided for the llree ends of the straight-edges,such locking dogs being slidably and pivotally mounted on rods 35 thatare secured to the framework of the table, andthe wing-like extensions36 thereof are movable into notches formed in the ends of thestraightedges, the sides of the members 36 of the notches being taperedor of V-form. Set screws 31 are provided for clamping the dog 34 inposition. The locking dogs serve to prevent deection of the free ends ofthe straight-edges when working with material upon the board.

In some instances, advertisements or the like have portions of thematter appearing on angular lines relative to other portions thereof,and it may be desired to position the negatives somewhat diagonally onthe board, and to insert printed matter in proximity thereto alongnondiagonal lines. Again, a plate negative may have had the exposuremade thereon in non-alignment with the edges of the plate. In order topermit of the desired angular positioning of the plates or negative insuch instances, I provide a straightedge 39 that rests upon a washer 40and is pivotally connected to the frame by a pin 4|. The lower end ofthe pin 4I is threaded for the reception of a clamping screw 42 wherebythe straight-edge 39' can be secured in' its various positions ofadjustment about its pivot 4|. An edge of a glass plate or the like willbe engaged by the inner edge of the member 39, so that the plate will besupported in desired angular positions upon the table. In case it isdesired to superpose one plate upon another, as indicated by dottedlines in Fig. 3, an additional straightedge member 43 is provided,secured to the straight-edge 39 by screws 44.

In Fig. 8 I show a protractor which can be employed with the straightedges of Fig. 1. 'I'he protractor comprises a straight-edge 45 that hasan upstanding boss 48 which extends into an opening in a protractorplate 46.4 An indicating arm 41 has key connection with the boss 48, sothat the members 45 and 41 will move as a unit. These members are heldin position upon the plate 46 by a clamp screw 49' that has threadedengagement with the boss. `A bar 50 is secured to the underside of theplate 46 in position to be engaged by the straight-edge 21. A cammingdisc or lock 5I is mounted upon the lower end of a button 52 thatextends through the plate 46, the camming disc being employed to lockthe protractor upon the straight-edge 21 through turning movement of thebutton. It will be seen that by means of the turn button 49 the straightedge 44 can be clamped in various angular positions, relative to theplate 46, and that the plate 46 can be readily set at various adjustedpositions along the straight-edge 21.

As shown in Fig. 1, rules or scale bars 53 are secured to the table andserve-as a convenient means for indicating the exact positions of thestraight-edges.

As shown in Figs. 10 and 11, the table is of substantially the formabove described and the straight-edges 55 and 56 which correspond to thestraight-edges of Fig. 1, and additional straight-edges 51 and 58 areprovided. Rules 59 and 60 are carried by the straight-edges 55 and 56respectively, and serve as a convenient means for determining the exactdistances apart of the various straight-edges.

Referring now to Figs. 13 and 14 I show a structure for4 use as anegative and plate registering device, for color negatives and plates,wherein aligning bars 62 are provided in lieu of or as supplemental ofstraight-edges. 'Ihese aligning bars are mounted upon guide rods in thesame manner as the straight-.edges of Figs. 1 to 7 and are movable tovarious positions upon the board. Each bar has mounted thereon adove-tail bar 63 that extends throughout the major portion of the guidebar. Slide blocks 64 have engagement with the bars 63 and carry setscrews 65 whereby the blocks can be clamped at adjusted positions uponthe bars 63. The lingers 66 are pivotally mounted upon the blocks 64 andare held in place thereon by clamp screws 61, the nut 61 having threadedengagement with the screw 65. The structure of Fig. 13 is particularlyuseful vas a registering device, which makes it possible to set up anynumber of color negatives or etched plates, so that proper registry forcolor printing can be eifected. Thus after adjustment of the lingers, aseries of negatives to be employed in making a plate for reproduction orprinting can be aligned and succeeding series of plates for other colorscan be similarly aligned, or the set up can be vduplicated for anotherseries for other colors.
